2 Claims.

This invention relates to improvements in toilets, and more particularly to an overflush mechanism for toilets which automatically let water into the flush tank to overfiow into the bowl, whenever the toilet seat is seated upon or raised up against the front of the tank, or by manually turning the handle of the flush operating mechanism in a direction opposed to that for normally flushing the bowl.

An object of my invention is to provide an improved apparatus which will cause an overflush of water from the water supply to a flush tank to create a flushing noise while the toilet is in use to overcome the natural noises, and as the movement or" the water being discharged into the bowl is in a downward direction, undesirable splash while in use is reduced to a minimum.

A further object of my invention is to provide an improved overflush mechanism for toilets, which when in operation will create a suction to draw cfi unpleasant odors, and which will constantly provide for a full tank of water for flushmg.

A still further object of my invention is to provicle an improved overilush mechanism for toilets which will be highly efiicient in operation and which will be quite inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawing which forms a part of my application;

Figure l is a partial sectional view through a flush tank showing my improved mechanism in- 33 corporatecl therein, and

Figure 2 is a side elevation of a toilet, showing the flush tank in section, and with my improved mechanism incorporated therein.

Like characters of reference are used through- 40 out the following specification and the accompanying drawing to designate corresponding parts.

In carrying out my invention, I provide a toilet seat I, hinged at 2 to a toilet bowl 3, which when not in use is adapted to be raised at a slight angle from the top of the top of the bowl.

A flush tank 4 of usual construction is pro vided, and is connected with the bowl 3 by the conduit 5. The tank 4 is further provided with the water inlet pipe ii, which has a lateral extension connected through a double acting valve '1', to the bowl 3. Arranged at the rear of the toilet seat I beyond the hinge 2, are a pair of angularly arranged valve operating arms 8 and 9, which cause the operation of the double acting valve I,

whenever the seat I is seated upon, or whenever the seat I is raised up against the front of the tank 4, thereby admitting water from the supply or inlet pipe 6 to enter directly into the bowl 3 while the toilet is in use, thereby producing a 5 flushing noise which will overcome the natural noises made when using the toilet and also create a suction in the bowl to draw off the odors therefrom, thus effectively ventilating the same.

The water inlet pipe 6 is connected to the bot- 10,

tom of the tank 4, and to the float operated valve I0, which is adapted to discharge water from the inlet pipe to the interior of the tank 4. The float II is pivoted above the valve ID by means of the linkage I2, and operates in the usual man- 16 her. However, the manually operated handle l3 at the top of the tank 4 is connected through the rod I4, and connected rod I5, to the pivoted finger [6, which when the handle I3 is turned in a left hand direction, bears on the rod H which 20 carries the float II, and causes the valve II) to admit more water, thereby raising the water level in the tank above the top of the overflow pipe I8, whereupon it will flow downwardly and into the bowl to cause an overflush for accomplishing the desired hereinbefore described purpose. When the handle I3 is turned in a right hand direction, the longer end of the rod M will raise the ball valve 20 from its seat 2 I, through the medium of the vertical rod 22, to which the rod I4 is connected, to cause the normal flushing of the bowl by discharging the tank full of water. Suitable guides 23 are provided and attached to the overflow pipe I8, for guiding the rod 22 to which the ball valve 20 is attached.

From the foregoing description, it will be apparent that I have devised an improved method of construction for automatically and manually accomplishing the overfiushing of a toilet, to produce a flushing noise when the toilet is in use, and to reduce the splash in the toilet, and to produce a suction whereby the odors from the toilet will be effectively withdrawn.

Many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

1. In combination with a toilet bowl and flush tank therefor, a combined water admitting valve and overflush valve incorporated in said tank, a. water supply pipe leading to said tank and said valves, a water connection between the water supply pipe and said bowl arranged exteriorly of said tank, and a seat operated valve connected in said last mentioned water connection between said water supply pipe and said bowl whereby water may be admitted to the bowl independently of the water in the tank whenever the toilet seat is raised or lowered to provide a. noise concealing and ventilating action for the bowl.

2. The subject matter as set forth in claim 1,

and manually operable means for selectively operating the usual tank flushing valve or the overfiush valve in the tank whereby additional water may enter the tank and overflow down the tank overflow pipe to the bowl to provide a noise concealing and ventilating action for the bowl.
